The new Bremont Supermarine Type 300 range responds to a demand for a professional dive watch in a slightly smaller iteration. The watches' namesake derives from the 1930's aircraft company, Supermarine, whose first ever Spitfire prototype the Type 300 led to one of Britain's most iconic aircraft. The new 40mm case of the Type 300 is also slimmer being only 13mm from sapphire crystal to case back featuring a uni-directional ceramic rotating bezel.
